The phase diagram of the SnSe2-Er2Se3 system is studied using differential thermal analysis, x-ray diffraction, microstructural analysis, and microhardness and density measurements. The SnSe2-Er2Se3 system is pseudobinary and contains two eutectics and two intermediate phases, Er2Sn 3Se9 and Er2SnSe5. At room temperature, the SnSe2-based solid solution extends to ≃4.5 mol % Er2Se3, and the SnSe2 solubility in Er 2Se3 is ≃2 mol %.
